Explore Mermaid Formal Dresses

Searching for mermaid formal dresses in Australia? One Honey Boutique curates designer mermaid dresses, mermaid gowns, prom dresses and fitted evening gowns from leading Australian and international designers.

A mermaid dress is known for its fitted silhouette through the bodice and body before flaring toward the lower skirt, creating a dramatic shape for formal occasions. Depending on the individual design, similar silhouettes may also be described as fishtail or trumpet dresses.

Whether you're choosing a gown for a Year 10 formal, Year 11 formal, Year 12 formal, prom, graduation, university ball, gala, black-tie event, wedding or milestone celebration, explore mermaid gowns across an extensive range of colours, fabrics and statement finishes.

Discover mermaid prom dresses and formal gowns featuring satin, sequins, glitter, crystals, beading, lace, tulle and luxe embellishments, alongside sleek minimalist dresses and dramatic statement designs.

Love a structured bodice? Explore our corset formal dresses for sculpted corsetry and statement gowns, including fitted styles that pair corset bodices with dramatic mermaid silhouettes.

Prefer a softer flowing silhouette? Discover our A-line formal dresses for fitted bodices with skirts that flow outward, creating a beautiful alternative to a close-fitting mermaid gown.
